Analog PMA Settings (Optional) for Dynamic Reconfiguration
The following parameters are available in the Analog PMA Settings (Optional) tab of the Transceiver Native
PHY parameter editor. Refer to Changing PMA Analog Parameters for more details. Refer to the Analog
Parameter Settings chapter for details about using the QSF assignments.

Value
cei_11100_lr to
Selects the analog protocol mode to pre-select the TX pin
xfp_9950
swing settings (VOD, Pre-emphasis, and Slew Rate). After
loading the pre-selected values in the Parameter Editor, if
one or more of the individual TX pin swing settings need to
be changed, then enable the option to override the Intel-
recommended defaults to individually modify the settings.
For details about QSF assignments for the analog settings,
refer to the Analog Parameter Settings chapter.
On / Off
Enables the option to override the Intel-recommended
settings for the selected TX Analog Mode for one or more TX
analog parameters.
0-31
Selects the transmitter programmable output differential
voltage swing.
Fir_pre_1t_neg,
Selects the polarity of the first pre-tap for pre-emphasis.
Fir_pre_1t_pos
0-16
Selects the magnitude of the first pre-tap for pre-emphasis.
Fir_pre_2t_neg,
Selects the polarity of the second pre-tap for pre-emphasis.
Fir_pre_2t_pos
0-7
Selects the magnitude of the second pre-tap for pre-
emphasis.
Fir_post_1t_neg,
Selects the polarity of the first post-tap for pre-emphasis.
Fir_post_1t_pos
0-25
Selects the magnitude of the first post-tap for pre-
emphasis.
Fir_post_2t_neg,
Selects the polarity of the second post-tap for pre-
Fir_post_2t_pos
emphasis.
0-12
Selects the magnitude of the second post-tap for pre-
emphasis.
slew_r0 to slew_r5
Selects the slew rate of the TX output signal. Valid values
span from slowest to the fastest rate.
Enable / Disable
Enables the power-distribution network (PDN) induced inter-
symbol interference (ISI) compensation in the TX driver.
When enabled, it reduces the PDN induced ISI jitter, but
increases the power consumption.
r_r1, r_r2
Selects the on-chip TX differential termination.
On / Off
Enables the option to override the Intel-recommended
settings for one or more RX analog parameters. For details
about QSF assignments for the analog settings, refer to the
Analog Parameter Settings chapter.
non_s1_mode,
Selects between the RX high gain mode (non_s1_mode) or
s1_mode
RX high data rate mode (s1_mode) for the Continuous Time
Linear Equalizer (CTLE).
